Introduction

Lactic ferments are living micro-organisms that play an essential role in our digestion and immune system. Used for centuries in the production of fermented dairy products such as yoghurt and cheese, these beneficial bacteria are now also available in the form of food supplements to boost our intestinal health. In this article, we'll explore the benefits of lactic ferments, their origin and their use as a dietary supplement.

The benefits of lactic ferments

Lactic ferments have many health benefits, particularly for our digestive and immune systems. Here are some of their main benefits:

• Improved digestion : Lactic ferments help maintain a healthy balance of bacteria in our intestines by preventing the proliferation of harmful bacteria. They can also improve digestion by breaking down food and aiding the absorption of nutrients. This can be particularly beneficial for people suffering from digestive problems such as bloating, gas and diarrhoea.
• Strengthening the immune system : Around 70 % of our immune system is found in our gut, and lactic ferments help maintain a healthy balance of bacteria in this part of our body. They can also stimulate the production of antibodies and boost our immunity to infection and disease.
• Improving mental health : There is a close link between our gut and our brain, and lactic ferments can also have a positive impact on our mental health. Studies have shown that these beneficial bacteria can help reduce stress, anxiety and depression by regulating levels of serotonin, also known as the 'happy hormone'.
• Protects against allergies and inflammation: Lactic ferments can also play a role in preventing allergies and inflammatory diseases such as Crohn's disease and ulcerative colitis. By maintaining a healthy balance of bacteria in our gut, they help regulate our immune system and reduce inflammation.

The origin of lactic ferments

Lactic ferments are living micro-organisms found naturally in our bodies and in many fermented foods such as yoghurt, kefir, sauerkraut and kimchi. The two types of bacteria most commonly used in the production of these foods are lactobacilli and bifidobacteria.

These bacteria were first discovered by French microbiologist Louis Pasteur in the 1850s, when he studied the fermentation process in dairy products. Since then, their use has spread throughout the world, particularly in probiotic foods and drinks.

Use of lactic ferments as a food supplement

Lactic ferments can also be consumed in the form of food supplements, often in powder or capsule form. These supplements may contain one or more types of beneficial bacteria and are generally taken orally.

Dietary supplements based on lactic ferments are particularly popular for people suffering from digestive disorders, allergies or needing extra immune support. They can also be useful in preventing the side effects of antibiotics, which can kill off the good bacteria in our intestines.

It's important to note that not all lactic ferment supplements are created equally and that it's essential to choose a high-quality product from a reputable brand. It is also advisable to consult a healthcare professional before starting to take lactic ferment supplements, particularly if you have any underlying health problems or are taking medication regularly.

Conclusion

Lactic ferments are beneficial bacteria that are essential for our intestinal and immune health. Consuming them can offer many benefits for digestion, immunity, mental health and the prevention of allergies and inflammatory diseases. If you're considering taking a lactic ferment supplement, make sure you do your research thoroughly and choose a quality product from a reputable brand. Don't hesitate to consult a healthcare professional for personalised advice. Take care of your gut and it will take care of you!
